Thank you everyone. Ted, your story is very similar to ours. Chopper was a rescued pit bull, he changed everyones views of pit bulls. He was an amazing soul, and had eyes like a human. In the last few days he was in severe pain, after x-rays yesterday, the vet told us he most likely had bone cancer in a hind leg that was causing excruciating pain. While at the vet he had four bouts of howling, wincing pain which was a telling sign he was ready to go. In the many years, i never heard this dog so much as wimper.
The vet gave us our options and we decided it was time to let him go. We were both distraught with grief as we let the vet sedate him in preparation for his journey to the other side. we spent the last ten minutes with him, and expressed our love for him. The vet administered the final injection and he went peacefully. My wife and i couldn't let him live in pain simply to comfort us, and everything in that dog told us it was time. He will be missed by all who knew him. A true best friend.
